Evaluating the influence of sulphur dioxide and nitrogen dioxide in ambient air on biochemical factors contributing to plant tolerance.

Air pollutants, specifically, Sulphur Dioxide (SO) and Nitrogen Dioxide (NO) cause numerous biochemical changes in plants; by studying the biochemical parameters, plant resistance against these pollutants can be evaluated. The effect of air pollutants on biochemical parameters such as ascorbic acid (AA), total chlorophyll (TC), pH and the relative water content (RWC) of leaves has been investigated in the present study. The objective of the present study was to observe the relationship between biochemical parameters of plants and ambient air pollutants (SO and NO).

Assessing the relationship between the biochemical and the morphological factors (leaf surface area and leaf surface texture) of industrial and roadside plants.

The study of biochemical parameters provides an idea of the resistance of plants against air pollutants. Biochemical and Physiological parameters are studied with the help of Air pollution tolerance index (APTI). Fifteen plant species were evaluated to assess biochemical and APTI from two polluted sites (Phagwara Industrial area and Phagwara Bus stand area).

Role of air pollution tolerance index (APTI) method for green belt development: a review.

Air pollution has emerged as one of the most important aspects of environmental research, as the progress of human civilisation has significantly deteriorated the quality of air. Plants have a significant role in maintaining and monitoring ecological balance by actively participating in the cycling of gases such as oxygen and carbon dioxide and nutrients. Besides, they also provide a large leaf base for assimilation and deposition of airborne pollutants to reduce their concentration in the atmosphere.

Development of emission factors for motorcycles and shared auto-rickshaws using real-world driving cycle for a typical Indian city.

Vehicular emission is one of the most important contributors of urban air pollution. To quantify the impact of traffic on urban air quality, it is necessary to quantify vehicular emission. In many cities of India, such as Dhanbad, shared auto-rickshaw is the pre-dominant mode of transportation.
