1。如何解释化石燃料导致人体暴露于重金属的使用，比较源，暴露甲基汞的影响途径和铅。包括至少2个参考。
有几个化石燃料引起的影响对人类不利的性质。汞和铅是环境毒物暴露也可能对人体产生可怕的影响这两种重金属。
源：
•甲基汞的来源是燃烧化石燃料主要是煤。这些都是大自然中汞的主要来源。
•铅是建筑和建筑材料的发现铅酸电池。这些人和他们的日常生活接触可高度危险（晴天，2010）。
暴露的途径：
•甲基汞可能通过鱼旗鱼，金枪鱼，鲨鱼的吸入暴露在人类，这种金属的出现等增加时更高的食物链，因此也对那些更高的食物链的消费者的不良影响。
•铅可能暴露在人类饮用受污染的水或咀嚼对象的含铅芯片。
影响：有几个严重影响甲基汞和铅对暴露人类。
•长期暴露于甲基汞可以导致心脏病发作导致成人心血管系统风险。这也导致一些发展问题的孩子，可能会导致精神损害是由于体内的金属高暴露（卡斯多帝，2003）。
•铅暴露会导致一些畸形造成儿童中枢神经系统的影响。接触铅可引起急性贫血，肌肉无力，和成人的脑损伤。

- Explain how the use of fossil fuels results in human exposure to heavy metals, comparing the source, pathway of exposure and impacts of methyl mercury and lead. Include at least 2 references.
There are several fossil fuels which cause several impacts on human beings which are adverse in nature. Methyl Mercury and Lead are the two heavy metals which are considered to be an environmental toxicant and exposure to the same may have terrible impacts to the human body.
Source:
- The source of Methyl Mercury is burning the Fossil Fuels mainly Coal. These are the main sources of methyl mercury in nature.
- Lead is found in construction material for building and lead-acid batteries. These are available in the everyday life of human beings and their exposures can be highly dangerous (Doney, 2010).
Pathway of Exposure:
- Methyl Mercury may be exposed to human through the intake of fish like swordfish, tuna, shark, etc. The advent of this metal increases as it moves higher up in the food chain and therefore also has adverse effects on the consumers who are higher up in the Food Chain.
- Lead may be exposed in humans by drinking contaminated water or chewing objects painted with lead based chips.
Impacts: There are several severe impacts which Methyl Mercury and Lead have on human beings with their exposure.
- Long term exposure to Methyl Mercury may result in a risk to the cardiovascular system resulting in Heart Attack in adults. It also causes several developmental issues in children that might lead to mental impairment due to high exposure of the metal in the body (Castoldi, 2003).
- Exposure to Lead may result in affecting the central nervous system in children thereby causing several deformities. Exposure of lead may cause acute anemia, muscle weakness, and brain damage in adults.
