Estimation of Gas Emissions using the LandGEM Model from the Landfill of Baft County, Kerman, Iran.

Over time, waste buried in landfills produces greenhouse gases (GHG) such as methane (CH) and carbon dioxide (CO). It is essential to know and investigate the type and amount of production of these gases from landfills as well as their effects, considering the environment's vulnerability to GHG. In the present study, the gases released from the landfill of Baft county were estimated using the landfill gas emissions model (LandGEM).

Non-carcinogenic and cumulative risk assessment of exposure of kitchen workers in restaurants and local residents in the vicinity of polycyclic aromatic hydrocarbons.

Polycyclic aromatic hydrocarbons (PAH) are often formed when organic substances do not burn completely. This study evaluates the non-carcinogenic and cumulative risks associated with PAH levels by testing blood and urine samples in kitchen workers and residents near restaurants in Shiraz, Iran. Metabolites of PAH in the urine samples as well as clinical parameters in the blood samples were measured.

Direct red 81 adsorption on iron filings from aqueous solutions; kinetic and isotherm studies.

Direct Red 81 (DR-81) dye with a very high water solubility is widely used in many industries particularly textile industries. This study aimed to evaluate the practicability of using iron filings for the adsorption of DR-81 dye from the aqueous solutions. The effects of pH, adsorbent dose, initial DR-81 dye concentration, and adsorption time on adsorption process were also evaluated.
