While it is usually a healthy source of protein in the diet，there may be several reasons to avoid biting into a forkful of fish. Before you break out the tartar sauce，learn some facts about fish to keep yourself and the environment healthy. Some fish may contain harmful chemicals，which can be the result of both natural causes and water pollution. Mercury is a poisonous chemical，which occurs naturally in oceans and the Earth’s crust，but also comes from manmade sources，such as pesticides，burning garbage，and the releasing of fossil fuels. Polychlorinated biphenyls (PCBs)，a group of chemicals，can also be found in some fish. These dangerous manmade chemicals were used in many industries until 1977，when they were banned. PCBs were released or leaked into the air and water and have been transported around the globe. How do mercury and PCBs end up in fish and the food supply? When they are released into the air，they attach themselves to particles. These particles settle on the ground and in the water and are eventually eaten by microscopic organisms. Small fish eat the microorganisms，and large fish eat the small fish and on up the food chain. Because they can negatively affect your health，the U．S. Environmental Protection Agency advises that kids younger than 15 years old avoid fish that contain high levels of mercury and PCBs. These include shark，swordfish，king mackerel，and tilefish. There are also many types of fish that are good for you，but because of overfishing are in danger of being wiped out. Some are being fished in the wild so much that they cannot reproduce fast enough to survive. Others are being farmed in ways that are not environmentally friendly. These fish include red snapper，Atlantic salmon，blue fin tuna，and king crab. Despite these problems，there are several fish that are both healthy and sustainable，such as Alaskan salmon，American catfish，Pacific cod，and several farmraised fish and shellfish. 【文章大意】 鱼虽富含蛋白质，但本文却建议小孩子不要吃鱼以及说明了其中的原因。 1．How do mercury and PCBs come to our food supply?
