The intergenerational impact of mothers and fathers on children's word reading development.

Background: Numerous studies have investigated the associations between the home literacy environment (HLE) and children's word reading skills. However, these associations may partly reflect shared genetic factors since parents provide both the reading environment and their child's genetic predisposition to reading. Hence, the relationship between the HLE and children's reading is genetically confounded.

Soil concentrations, occurrence, sources and estimation of air-soil exchange of polychlorinated biphenyls in Indian cities.

Past studies have shown potentially increasing levels of polychlorinated biphenyls (PCBs) in the Indian environment. This is the first attempt to investigate the occurrence of PCBs in surface soil and estimate diffusive air-soil exchange, both on a regional scale as well as at local level within the metropolitan environment of India. From the north, New Delhi and Agra, east, Kolkata, west, Mumbai and Goa and Chennai and Bangalore in the southern India were selected for this study.
