Batch kinetic and inhibition studies were performed for the aerobic cometabolism of 1,1,1-trichloroethane (1,1,1-TCA), 1,1-dichloroethylene (1,1-DCE), and 1,1-dichloroethane (1,1-DCA) by a butane-grown mixed culture. These chlorinated aliphatic hydrocarbons (CAHs) are often found together as cocontaminants in groundwater. The maximum degradation

Occupational allergy and asthma is a challenging issue in the developing countries. Chemicals inhaled in the workplaces may act not only as allergens but also as immune response modifiers, contributing to asthma exacerbation. In this study, we tested the adjuvant

1,1-Dichloroethylene (DCE) causes pulmonary injury that is characterized by necrosis of bronchiolar Clara cells. Mitochondria have been identified as an early target in the toxic response. Because mitochondria have been implicated in both necrotic and apoptotic cell death, we have
