Book Description
Chemical Contaminants in Human Milk contains a comprehensive, up-to-date global review of the contamination of human milk with environmental and occupational chemicals. The book covers many different aspects of this problem, including the extent and benefits of breast-feeding, the transfer of chemicals into breast milk, analytical methodologies used in human milk studies, the levels of chemical contaminants in human milk, and geographical variations and time trends in levels. The many different factors that can influence the levels of contaminants in breast milk are also discussed. Other important topics examined include human milk contamination due to exposure of the mother at the workplace and the risk to her baby, the intake of toxic chemicals by breast-fed infants, calculated intakes and official limit values, the toxicological implications of human milk contamination based on available data from animal experiments and human studies. The book concludes with an overall assessment of the current situation, together with recommendations for future work. Chemical Contaminants in Human Milk is a valuable source of information for pediatricians and other health professionals, policy makers involved with ensuring the health and welfare of infants and nursing mothers, nursing mothers and organizations involved in the promotion of breast feeding, and individuals and organizations involved with the study and control of environmental pollution and occupational hygiene.

Book Description
That residues of pesticide and other "foreign" chemicals in food stuffs are of concern to everyone everywhere is amply attested by the reception accorded previous volumes of "Residue Reviews" and by the gratifying enthusiasm, sincerity, and efforts shown by all the in dividuals from whom manuscripts have been solicited. Despite much propaganda to the contrary, there can never be any serious question that pest-control chemicals and food-additive chemicals are essential to adequate food production, manufacture, marketing, and storage, yet without continuing surveillance and intelligent control some of those that persist in our foodstuffs could at times conceivably endanger the public health. Ensuring safety-in-use of these many chemicals is a dynamic challenge, for established ones are continually being dis placed by newly developed ones more acceptable to food technologists, pharmacologists, taxicologists, and changing pest-control requirements in progressive food-producing economies. These matters are of genuine concern to increasing numbers of governmental agencies and legislative bodies around the world, for some of these chemicals have resulted in a few mishaps from improper use. Adequate safety-in-use evaluations of any of these chemicals per sisting into our foodstuffs are not simple matters, and they incorporate the considered judgments of many individuals highly trained in a variety of complex biological, chemical, food technological, medical, pharmacological, and toxicological disciplines.

Book Description
This open access book reviews the trends of persistent organic pollutants (POPs) in human milk and discusses the main findings of five global surveys that were coordinated by the World Health Organization (WHO) and the United Nations Environment Programme (UNEP) from 2000 to 2019. Human milk was selected as core matrix for human exposure under the Global Monitoring Plan for effectiveness evaluation of the Stockholm Convention on Persistent Organic Pollutants. Milk from well-defined groups of mothers was collected and mixed to form a representative sample per country. Datasets collected represent the largest global human tissues survey with a harmonized protocol, carried out in a uniform format for more than two decades. Altogether 69 countries participated in these studies between 2000 and 2015, and more than 40 countries participated in the study from 2016 to 2019. Divided into 5 parts, the book offers an authoritative overview of human milk biomonitoring; collates the harmonized sampling requirements and analytical methods for the identification and quantification of contaminants in human milk; examines the results of the WHO/UNEP-coordinated exposure studies, including the identification of selected chlorinated pesticides, dioxin-like compounds, industrial chemicals like polychlorinated biphenyls (PCB) and chlorinated paraffins, polybrominated POPs and PFAS, among others; and traces geographic, temporal and cross-substance trends and correlations, and human health risks. The book finishes by providing the reader with the summary of the main findings and outlook from these studies, in which the comparison of concentrations found for the wide range of POPs listed in the Stockholm Convention allowed the identification of possible needs for actions and follow-ups in different countries/regions. This book contributes to the understanding of exposure to hazardous chemicals and pollution as addressed by the UN Sustainable Development Goals on Good Health and Well-being (SDG 3) and will appeal to environmental and analytical chemists, researchers, professionals, and policymakers interested in learning more about contaminants in human milk. Given its breadth, this book will also appeal to a broader audience interested in maternal and child health.

Book Description
The third and final volume in a series of reports stemming from a multi-national study on breast-feeding (see also Contemporary Patterns of Breast-feeding and The Quantity and Quality of Breast Milk). Responding to inconsistencies in the published data on concentrations of trace elements in breast milk, the study analyzes milk samples collected from women in Guatemala, Hungary, Nigeria, the Philippines, Sweden and Zaire in an effort to obtain reliable data on the quantities of minor and trace elements present in breast milk. The study was also designed to determine whether the concentrations of these elements varied significantly with the socioeconomic group, geographical origin, or nutritional status of the mothers. The book opens with a brief explanation of the biochemical functions of trace elements and the association of deficiencies with various disorders of growth and development. The second chapter explains the careful design of the study, which used standardized procedures for the collection of samples, a single reference analytical laboratory for each element, and appropriate analytical reference materials. Results are then presented for total dry matter and for antimony, arsenic, cadmium, calcium, chlorine, chromium, cobalt, copper, fluorine, iodine, iron, lead, magnesium, manganese, mercury, molybdenum, nickel, phosphorus, potassium, selenium, sodium, tin, vanadium, and zinc. For each element, information is given on any observed differences between study areas, variations in samples between urban and rural areas, and variations in concentrations according to time of year. A discussion of findings compares results of the study with data from the literature, assesses sources of variation in the elemental composition of human milk, and compares the observed daily intake of minor and trace elements with recommended intake. The book concludes that when minor and trace elements are determined under similar conditions in the breast milk of groups of mothers living in different parts of the world, environmental conditions play a major role in determining concentrations. Findings from the study should also prove useful in the formulation of recommendations regarding levels of trace elements in the diet of infants.

Book Description
How many times have we thought with concern about the possible contamination of food? Pollution, agricultural treatments, technological treatments, and packaging are the best-known human sources of toxic substances as food contaminants. The present book contains 11 original research papers representing various approaches of identifying and measuring toxic residues in food materials. The analytical determination of food contaminants is an indispensable tool in characterizing the adverse effects and unexpected toxicity related to food intake. No risk assessment would be possible without data from the analysis of food contaminants. This Special Issue is an interesting overview of recent methods and is highly representative of a broad worldwide outline, collecting authors from ten different countries and four continents. Very different toxics are described, from volatile organic compounds to heavy metals and from highly polar chemicals to classical organic contaminants. A wide range of analytical techniques are portrayed, including sample preparation and clean-up methodologies, classical chromatographic and hyphenated spectroscopies, and the latest high-resolution mass spectrometry applications. The presented works consider a varied selection of foods: the studied matrices are meat, fishery products, fruits, and miscellaneous beverages.

Book Description
Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.

Book Description
A brilliant writer, first-time mother, and respected biologist, Sandra Steingraber tells the month-by-month story of her own pregnancy, weaving in the new knowledge of embryology, the intricate development of organs, the emerging architecture of the brain, and the transformation of the mother's body to nourish and protect the new life. At the same time, she shows all the hazards that we are now allowing to threaten each precious stage of development, including the breast-feeding relationship between mothers and their newborns. In the eyes of an ecologist, the mother's body is the first environment, the mediator between the toxins in our food, water, and air and her unborn child.Never before has the metamorphosis of a few cells into a baby seemed so astonishingly vivid, and never before has the threat of environmental pollution to conception, pregnancy, and even to the safety of breast milk been revealed with such clarity and urgency. In Having Faith, poetry and science combine in a passionate call to action.A Merloyd Lawrence Book
