Ngay cả trong sự phụ thuộc xây dựng, môi trường nước, không khí, và các nguồn tài nguyên thiên nhiên là cơ sở chất lượng cao đời sống nhân dân nhằm mục đích để thưởng thức trong xã hội hiện đại. Tất cả mọi người đòi hỏi phải có nước sạch để uống, nấu ăn, thủy lợi, và vui chơi giải trí. Khi không khí bị ô nhiễm, ảnh hưởng đến hơi thở của mọi người, trong một số người kích thích suy hô hấp và ảnh hưởng đến chức năng tim | 5 The State of the Science Environmental Risks Jo Anne Shatkin CONTENTS Antimicrobial Antimicrobial Properties of Nanoscale Titanium Dioxide TiO2 .80 Short-Term Toxicity Daphnia LC50 Studies of Nanomaterial Toxicity to Buckyballs and TiO2 in Arsenic and Field Environmental Nanoscale Zerovalent Cerium Risk NIOSH The International Life Sciences Institute Risk Sciences Institute Summary and References .93 Even in the built environment reliance on water air and natural resources is the basis of the high quality of life people aim to enjoy in modern society. Everyone requires clean water for drinking cooking irrigation and recreation. When the air is polluted it affects everyone s breathing in some people stimulating respiratory distress and affecting heart functioning. The food supply is impacted when land and water resources are contaminated. As humans we exist as part of earth s ecosystem as animals in the food chain. Humans are not quite at the top but we are near it particularly urban 77 2008 by Taylor Francis Group LLC 78 Nanotechnology Health and Environmental Risks dwellers. We rely on all of the lower levels of the ecosystem to function in order for us to survive. Beyond the food chain people are impacted by the health of plants and animals in many ways. Consider the following issues 1 environmental contamination can change the health of the world around us and thus the resources humans depend on 2 people rely on the environment and because human activities often affect the environment attention to the impacts of development on the world around us is necessary 3 ecological impacts can be sentinels that is observation of toxicity to fish and other aquatic organisms can be an indicator of adverse effects on .
