With the economic development of China, air pollutants are also growing rapidly in recent decades, especially in big cities of the country. To understand the relationship between economic condition and air pollutants in big cities, we analysed the socioeconomic indictors such as Gross Regional Product per capita (GRP per capita), the concentration of air pollutants (PM10, SO2, NO2) and the air ...

background the amount of effective ingredient production in plants is influenced by various climatic and environmental factors such as quality of water resources, soil quality, air quality, and the level of environmental pollutants. objectives in this research, we seek to study and analyze the qualitative effects of heavy metals on the respiratory organ of rosemary. further, we will compare the...

As a huge threat to the public health, China's air pollution has attracted extensive attention and continues to grow in tandem with the economy. Although the real-time air quality report can be utilized to update our knowledge on air quality, questions about how pollutants evolve across time and how pollutants are spatially correlated still remain a puzzle. In view of this point, we adopt the P...

Photochemical smog is the result of complex chemistry taking place when sunlight irradiates the atmosphere laden with organic gases and nitrous oxides. High temperatures and bright sun light favour photochemical smog. The secondary pollutants, formed from the organic gases and nitrous oxides, are more aggressive and dangerous as the first pollutants. Secondary pollutants are O3, organic nitrate...

Laboratory research in toxicology has progressed far beyond reliance on measures of mortality to make use of sophisticated behavioral preparations that can evaluate the consequences of sublethal toxicant exposure. In contrast, field studies have not evolved as rapidly. Approaches developed by experimental psychologists and ethologists provide powerful and complementary methodologies to the stud...

BACKGROUND It took over two decades to achieve the removal of leaded gasoline in this country. This was despite international evidence and original research conducted in New Zealand on the harm to child cognitive function and behaviour from lead exposure. OBJECTIVE To identify lessons from the New Zealand experience of removing leaded gasoline that are potentially relevant to the control of o...
