| 食品調査値 | Levels of alpha-, beta-, and delta-hexachlorocyclohexane in food items(1). [Table#3331]Hexachlorocyclohexanes (HCH) were detected in composites of 4 market baskets for adult total diet analysis in the US for fiscal year 1978 at 0.001-0.002, trace, 0.002-0.007, 0.004-0.006, 0.006-0.026, not detected-0.001, trace-0.002, trace-0.002, trace, trace-0.004, not detected-0.005, not detected-0.001, trace-0.002, not detected-trace, not detected-0.002, 0.001-0.003 and not detected-0.001 ppm in ice cream, cottage cheese, processed cheese, natural cheese, butter, ice milk, roast beef, hamburger, pork chops, fish filet, fish (canned), lunchmeat, frankfurters, liver, round steak, veal and lamb, respectively(1). Total HCH was found in 17 of 612 rice samples imported into the US between 1993 and 1994 at a maximum concentration of 0.02 ppm(2). HCH was not detected in fish sausage, chicken or eggsbut was detected in sea bream (3.38 ug/kg), horse mackerel (0.51 ug/kg), salmon (1.56 ug/kg), young yellowtail (8.68 ug/kg), shrimp (0.44 ug/kg), salted salmon (0.14 ug/kg), short-necked clam (0.02 ug/kg), salted salmon (0.69 ug/kg), canned (1.36 ug/kg), seasoned (0.10 ug/kg) and fresh tuna (0.21 ug/kg), fish paste products (0.23 ug/kg), beef (1.37 ug/kg), pork (2.41 ug/kg), sausage (14.00 ug/kg), cows milk (0.60 ug/kg), processed cheese (0.59 ug/kg) and ice cream (14.00 ug/kg) in Fukuoka, Japan in 1992-1993(3). It was detected in 52 of 54 of potato samples collected Mar 1991-Jan 1992 from local Kafr El-Zayat markets in Egypt at 0.0007-1.13 ppm(4). HCH was detected at 0.094 and 0.093 mg/kg fat basis in 355 cow's milk and 448 natural butter samples purchased from supermarkets in Veracruz City, Mexico in 1996(5). Median concentrations of total HCH in food products collected June-Sept 2007 from supermarkets in Iasi, Romania were reported as 2.5, 0.5, 0.55, 1.2 and 2.2 ng/g wet weight in beef, chicken, pork, salami and pork sausagein butter, cheese (sheep), cheese (cow), milk cream, vegetable oil and eggs median concentrations were 20.5, 10, 5.3, 13.5, 0.9 and 0.5 ng/g wet weight, respectively(6).Three types of edible oil (mustard, groundnut, sunflower) were sampled from nine cities in India in April 2004total hexachlorocyclohexane concentrations were reported as follows(1):[Table#3332]Hexachlorocyclohexane was detected in food products collected Aug to Oct 2007 from 10 markets in 3 regions of Hong Kong, China at the following concentrations (ng/g wet weight)(1):[Table#3333]Composite results of 4 market basket samples, adult total diet, October 1977 - September 1978: ice cream - 0.001-0.002 ppm, cottage cheese - trace, processed cheese - 0.002-0.007 ppm, natural cheese - 0.004-0.006 ppm, butter - 0.006-0.026 ppm, ice milk - not detected-0.001 ppm, roast beef - trace-0.002 ppm, hamburger - trace-0.002 ppm, pork chops - trace, fish filet - trace-0.004 ppm, fish (canned) - not detected-0.005 ppm, lunchmeat - not detected-0.001 ppm, frankfurters - trace-0.002 ppm, liver - not detected-trace, round steak - not detected-0.002 ppm, veal - 0.001-0.003 ppm, lamb - not detected-0.001 ppm(1). |
