A review on effect of air pollutants on fetal development and pregnancy outcomes
Journal of Air Pollution and Health, 2019 Developing fetus is connected to the mother by placenta to receive oxygen and nutrients. Maternal exposure to ambient air pollution not only affects maternal health but also provides a pathway for many toxic pollutants to cross the placental barrier and ...

Identification of organic pollutants in city atmospheres
Clean Air Journal, 1973 A suitable gas chromatophic analytical technique is described for the characterization of organic components in air samples from traffic dense areas. The method employs a chromosorb 102 cold trap to collect and concetrate samples and a 30 metre SCOT DC ...

Air pollution modelling for birth cohorts: a time-space regression model [PDF]
, 2016 To investigate air pollution effects during pregnancy or in the first weeks of life, models are needed that capture both the spatial and temporal variability of air pollution exposures.; We developed a time-space exposure model for ambient NO2 ...

Effect of biochar and liming on soil nitrous oxide emissions from a temperate maize cropping system [PDF]
SOIL, 2015 Biochar, a carbon-rich, porous pyrolysis product of organic residues may positively affect plant yield and can, owing to its inherent stability, promote soil carbon sequestration when amended to agricultural soils.

Advanced Engineering Materials, EarlyView.Sustainability assessment requires methodologies that appropriately distinguish between additive and non‐additive material properties. A toxicity‐weighted scoring system is developed and applied that accounts for the disproportionate influence of highly toxic constituents through nonlinear weighting functions, providing more realistic estimates than ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Biochemical Changes among Medical Laboratories Staff Occupationally Exposed to Formaldehyde Vapors
Journal of High Institute of Public Health, 2010 Background: Increased levels of tumour markers: carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC -Ag), Alpha feto protein (AFP), and neuron-specific enolase (NSE) may indicate the onset of the carcinogenic process.
