In’ mining. mercury was in Wide spread use to separate gold and silver from the ore in the early 20th Century. It is still used in some gold mines but in a controlled manner. However, more mercury is still being found in disposal areas from gold, silver and There were six Chlor- alkali plants using mercury in Ontario in 1970. These plants were ordered to curtail mer- cury losses. All of them complied and con- tamination dropped from several pounds per day to a few ounces. Use of mercurial slimicides by pulp and paper mills was stopped in 1970. The Government's information package on this problem points out that since contaminants were first discovered in fish in the 1960s Governâ€" ments have developed extensive monitoring programs to detectI contamination and have used their powers to restrict the manufacture or use of the offending substances. Apart from industrial pollution fish can only become contaminated by mercury from natural sources from con- centration of mercury naturally occuring as mineral deposits in the bedrock. Metal mercury is the most widely found toxic pollutant although man- made materials such as DDT, mirex and polychlorinated biphenyls (PCB) have also been found in fish in dangerous amounts. Fish in many parts of the world have been af- fected by natural and industrial contaminants and as an industrialized Province. Ontario has not escaped this problem. Information about the water in which you plan to fish can be obtained from Regional and District Offices of the Ministry of the Environment and Natural Resources, or by writing to the Ministry of Environment Informa- tion Services Branch, 135 St. Clair Ave. West, Toronto, Ontario, M4B 1P5. Fish should not be taken home for freezing and eating unless it is from the totally safe category. Children under 15 and women of child bearing age should eat only those fish designated as totally safe and it should be remembered that a meal is considered equivalent to 230 grams or 8 ounces. Anyone fishing on, and off, for more than three weeks during the year and eating their catch. should consider them- selves a long term con» sumer according to charts or information given concerning the waterways. Members of the public are urged to check their catch, to identify species, to measure length of fish, and to check charts for the respective lake or waterway to make sure of the amount of such fish safe for human con- sumption over a specific period. â€" some in limited quantities only. However, others should be avoided. Where there are problems. many species of fish are still safe to eat The Ontario Govern- ment has released an information package on the contamination of fish in Ontario waterways. Signs are to be posted at public access points where some species of fish are known to be contaminated.
