Walnut Creek, California

The results of a 12 week pilot mixed plastic curbside collection program in Walnut Creek. California are shown in Table 2.9. Plastic types collected were any clean film or rigid plastic container. Also shown in the table is the fraction of non-plastic components or trash. Four samples of 1,300 pounds each were characterized by hand sortation and physical and chemical tests. The average generation rate was reported to be 0.16 pounds/person/day.

Measurements were made using two types of passive track-etch alpha dosimeters. One of them was the bare detector of CR-39. After exposure these dosimeters were etched by 30 % NaOH at 70°C for 5 hours. The number of pits was scored under a microscope with a television camera in Shiga University of Medical Science. Methods of calibration and adjustment for deposition of radon daughters introduced by Yonehara (Yonehara et al., 1986) were adopted. The second detectors were Terradex type SF (Alter and Price, 1972). These detectors consist of a plastic cup, covered by a filter to allow entry only of gases, with a track-etch detector inside. The reading of results was carried out by Terradex Corp. in Walnut Creek, California, U.S.A.. The measurements of radon concentration were carried out by both methods in each location, except for Hokkaido where the measurements were done only by Terradex. However, the data obtained by CR-39 detectors will be mainly presented in this paper, because the two methods did not give identical results as separately reported in this proceedings by Yonehara et al. (Yonehara et al., 1986).

Chemicals in lakes and streams caused 46 states to issue public health warnings to avoid or curtail the eating of fish. Mercury was the cause in 60% of the cases, polychlorinated biphenyls 22%, chlordane (a banned chlorinated insecticide) 7%, DDT 2%, the remainder being spread over 25 chemicals.182 Fish advisories went up 26% from 1995 to 1996 to the point where 15% of the lakes and 5% of the rivers in the United States are now covered.183 In fairness to industry, it should be pointed out that a study by the Lindsay Museum, in Walnut Creek, California, found that 70% of the chemicals in San Francisco Bay came from the daily activities of ordinary people (e.g., oil from leaky cars, copper dust from brake pads, garden fertilizers, and pesticides).184 Nearly 50% of the oil in the world s waters comes from people carelessly discarding used oil on the ground or down drains.185 Sixty-six percent of Delaware...
