With the development of offshore and Pelagic Fisheries, continuous expansion fishing routes, corresponding ship tonnages are increasing, air pollution vessels is becoming more serious. An fishery research vessel was selected as object, emission factors were obtained according to its basic data, method based on fuel consumption adopted calculate pollutants (NO x , HC, CO PM 10 ) inventory establ...

In this paper, a nonlinear dynamical model is proposed and analyzed to study the survival of biological species in a polluted environment considering the effect of environmental tax which can be used further to improve environmental quality. The environmental tax is imposed to control the emission of pollutants/toxicants only when the equilibrium concentration of pollutants go beyond its thresh...

With most eastern Chinese cities facing major air quality challenges, there is a strong need for city-scale emission inventories for use in both chemical transport modeling and the development of pollution control policies. In this paper, a high-resolution emission inventory (with a horizontal resolution of 3× 3 km) of air pollutants and CO2 for Nanjing, a typical large city in the Yangtze Rive...

Waste disposal in the current situation, which quantity and variety of waste are increasing, needs not only effective management principles but also depends on environmentally-friendly methods to put as less environmental footprint as possible. This study aims to assess the energy consumption, emission of greenhouse gases and air pollutants which normally produce during various waste management...

Major pollutants emission from Direct-Injection (D.I) diesel engines are predicted by means of a mathematical model. In order to construct such a model, an integral Multi-Zone Combustion Model (MZCM) is formulated, which basically consists of jet mixing and combustion submodels. In MZCM, variation of injection pressure is considered. Also time period of ignition delay is predicted by considerin...

Breast cancer incidence is higher in urban areas and industrialized countries, rather than in less developed ones [1]. The etiology is probably multifactorial and lifestyle and environmental factors account for 73% of cases [2]. The present study analyzes the eventual relationship between environmental pollutants exposure and population density and the risk of developing breast cancer. It conce...
