N.Y. state begins 5-year Love Canal health study that includes noncancer effects

Article Abstract:

A comprehensive five-year study of the health status of current and former residents of Love Canal, New York will be conducted by the state government. The New York State Department of Health aims to know the implications of the toxic wastes dumped in the "canal" to the general health of the Love Canal residents. The "canal," which is actually a trench about 60 feet wide and almost a mile long, contains more than 20,000 tons of toxic chemicals. The results of the study will help determine whether reports of heart diseases and cancer can be linked to the residents' chronic exposure to the toxic wastes.

EPA reassessment finds as much as 20 times less cancer risk from PCBs

Article Abstract:

An EPA draft reassessment suggests that polychlorinated biphenyls (PCBs) may not be as harmful as previously thought. PCBs comprise 209 chemicals that are widely found in the environment. They were banned from production in the mid-1980s after studies linked PCBs to cancer development. However, most of the studies focused only on one potent PCB which is Aroclor 1260. With the new data, it is shown that PCBs only have two-thirds to one-twentieth the potency claimed in previous cancer studies. The draft reassessment will be published as a final report in Sep. 1996.

"Transgenic" mice scrutinized as faster, cheaper cancer probe

Article Abstract:

Recent studies conducted by the National Toxicology Program (NTP) provide evidence that transgenic mice are more effective and less costly than other tools as a cancer probe. The NTP claims that carcinogenicity and toxicity testing in mice yield results in six months at a cost of $150,000 compared to bioassays which require two years for completion at a cost of between $2 million and $4 million. However, researchers caution that genetically modified mice may have altered metabolism or other biological process that may influence research results.
