Mangrove ecosystem is a very unique ecosystem in the Earth, which is under threat due to habitat loss, aquaculture expansion, overharvesting and increase of pollution load. In this review paper, world-wide status of mangrove habitat loss, the role of mangrove to act as a sink of pollutants and carbon capture (carbon sequestration), accumulation and biomagnifications of heavy metals is discussed...

China’s socioeconomic transitions have dramatically accelerated its economic growth in last three decades, but also companioned with continuous environmental degradation. This study will advance the knowledge of heavy metal water pollution in China from a spatial–temporal perspective. Specifically, this study addressed the following: (1) spatial patterns of heavy metal water pollution levels we...

Background and Purpose: In the environment, heavy metals in high concentration are toxic to most organisms. Human activities have continuously increased the concentration of these metals in the environment such as soils. In the present study, soil samples collected from Ahvaz IV industrial estate in Khuzestan Province. Materials and Methods: The soil samples were taken from 9 ...

We use a global chemical transport model (GEOS-Chem) driven by the GISS GCM to investigate the effect on China’s ozone air quality from 2000-2050 global changes in climate and anthropogenic emissions of ozone precursors. The climate and emission effect in combination will increase afternoon mean surface ozone over China by an annual average of 8.7 ppbv, of which 65% is attributed to the project...

In this short communication we describe the temporal variation of PAHs fingerprints and burden in surface soils from coastal and central valley sites in South Central Chile, with different anthropogenic influence. PAHs were extracted with accelerated solvent extraction and measured by HPLC with fluorescence detection. Levels of ∑ 15 PAHs were relatively low in both sites ranging between 190 to ...

[1] The impact of Southern California (SoCal) anthropogenic emissions on ozone (O3) in the mountain states in May 2010 is studied using the Sulfur Transport and Deposition Model. We identified two to six major transport events from SoCal to different subregions in the mountain states, with transport times of 0–2days indicated by trajectories, time-lag correlations, and forward/adjoint sensitivi...
