AIRO NATIONAL JOURNAL VOLUME 5 ISSN 23213914 A STUDY ON EFFECTS OF INDUSTRIAL POLLUTION OM RED GRAM (CAJANUS CAJAN(L) ) CROP AT KURNOOL AT ANDHRAPRADESH Submitted by : SHRI DEKBIN YONGGAM Research Scholar ; Botany 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 AIRO NATIONAL JOURNAL VOLUME 5 ISSN 23213914 of plants (Ashenden & Williams, 1980; Mejstrik, 1980; Anda, 1986). Leaf is the most sensitive part to the air pollutants (Lal & Singh, 1990). Analysis State Year Percentage of Pollution Andhra Pradesh 2009 52% Andhra Pradesh 2010 65% Andhra Pradesh 2011 29% General Analysis on the form of Standard Mean 41.2% 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 AIRO NATIONAL JOURNAL VOLUME 5 ISSN 23213914 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. References 1.
