Abstract
In a general scenario the effects of industrial pollution om red gram at Kurnool at Andhra
Pradesh we have certain survey data to analyze and determine the facts of the study . In this
continuation we have to present a carried out data at Kurnool, Andhra Pradesh, India just to
reveal the effect of pollutants releasing from an industry on physiology of Cajanus cajan (L.), a
pulse yielding crop of Fabaceae. The total chlorophyll content, ascorbic acid, relative water
content and P H of the leaf extract was measured following the standard methods. On basis of
them the Air pollution tolerance index (APTI) of the crop was calculated for two leaf samples,
one collected from polluted field of industrial area and another from a nearby unpolluted village
field. The study revealed an increase in APTI of the leaves collected from polluted site. The
percentage increase in APTI was 13.14. This indicates the tolerance capacity of the crop to a
polluted smoke releasing from the industry and the crop may be recommended to the farmers of
urban area for their economic growth. Indian cities are being exposed to high levels of air
pollution and people living in these cities are paying a price for the deterioration in air quality.
The serious problem is with airborne particulate matter (Agarwal et al.1999) due to
industrialization and urbanization.
Introduction
The pattern of economic growth is becoming increasingly associated with environmental
pollution. Agricultural crops can be injured when exposed to high concentrations of various air
pollutants. Injury ranges from visible markings on the foliage, reduced growth and yield to
premature death of the plant. The pollutants can cause a serious threat to the overall physiology

of plants (Ashenden & Williams, 1980; Mejstrik, 1980; Anda, 1986). Leaf is the most sensitive
part to the air pollutants (Lal & Singh, 1990).

Findings and Summary
The content values of total chlorophyll, ascorbic acid, relative water and PH along with the
calculated APTI for both the samples of site-1 and site-2 and percentage increase in APTI are
given in a table. Agbaire & Esief, 2009 reported that the plants show alteration in the
biochemical processes or accumulation of certain metabolites by the affect of certain pollutants.
In this study, changes in four parameters such as total chlorophyll content, ascorbic acid, relative
water content and PH of leaf extracts are used to determine the air pollution tolerance index in
Cajanus cajan. In industrial site sample the ascorbic acid concentration is higher than in village
site sample. The reducing activity of ascorbic acid is directly proportional to its concentration
(Raza & Murthy, 1988) and it is PH dependent. In present study, concentration of ascorbic acid
and PH of the leaf extracts is high in industrial sample supporting the studies of Agbaire & Esief
(2009). Chlorophyll content is an index of productivity of plant (Raza & Murthy, 1988). In
present study total chlorophyll is high in sample of Industrial site than in village site. Allen et
al.1987 demonstrated the increasing levels of total chlorophyll by certain pollutants. So, increase
in chlorophyll content of the leaves in industrial site may be attributed to the influence of

pollutants present in a smoke releasing from the industry. According to the studies of Dedio,
1975 the relative water content in a plant body helps in maintaining its physiological balance
under stress conditions of air pollution. Thus, the higher relative water content in industrial site
sample may be responsible for normal functioning of biological processes in plants at industrial
site.
