Identifying toxic chemicals is important for safeguarding human health. This report outlines a strategy to improve regulators’ ability to evaluate concerns that certain chemicals might cause hormone-related health effects at low doses. Two evaluation approaches of the strategy—systematic review and evidence integration—are demonstrated with data from animals and humans on two classes of endocri...

As other deyeloping countries, Thailand has a great demand for chemicals to be used in industry as well as for other various purposes. Most chemicals used in Thailand are imported from developed or industrialized countries with the avarage of 600,OOO metric tons per year. Pesticides are recognized as a major group of imported chemicais. Chemicals which have been regarded as industrial toxic sub...

Environmental impacts caused by tin and copper based commercial antifouling (AF) paints were proved to be detrimental to aquatic ecosystems. Therefore, a search of environmental friendly AF compounds to be used in marine paint to protect the surface of maritime developmental structures from the unwanted biofouling is a burning issue of the present time. Commercially available eight organic chem...

If you saw a low-lying cloud that was labeled clearly with its contents, and the label contained the words benzene, carbon monoxide, formaldehyde, hydrogen cyanide, methane, phenol, styrene, and toluene, would you go out of your way to walk through that cloud and inhale those toxic chemicals? Of course not. But you expose yourself to these same toxic chemicals each time you participate in a sur...

Introduction Many of the substances used as food additives possess no outstanding toxic property; others which may be used as adjuncts in processing may be toxic but are present in the food only in very small quantities. The study of non-toxic substances resolves itself into the problem of trying to prove a negative. An experimental investigation of the toxicity of many of the chemicals used in...

ubiquity of toxic substances in the environment continues to be a significant public health concern. Body burdens of chemicals such as dioxins, methyl mercury, PCBs, and a range of the " usual suspects " are the increasingly represented norm rather than the exception in the U.S. population. In the recently released National Exposure Report (National Center for Environmental Health 2003), which ...

The state of Massachusetts enacted the Toxic Use Reduction Act (TURA) in 1989. The law requires that users of toxic chemicals evaluate and plan for pollution prevention. Data indicate that shipment of toxic chemicals as product have been reduced by over 30 % and that releases of toxics have declined over 80% during the first ten years of reporting. Analysis of the data for several chemicals des...
