Investigative study on macroinvertebrates and pollution tolerance index of four rivers in the derived savannah belt of Edo-North in Southern Nigeria was carried out from January to December, 2010. The study involved monthly field sampling and laboratory analysis of macrofauna. The objectives of the study were to evaluate the biodiversity status and importantly, the environmental integrity of the four selected rivers. Two dominant macroinvertebrate families were recorded; Baetidae and Chironomidae while, 53 macroinvertebrate taxa were identified across the rivers. The highest number of species (12) was recorded for Diptera, while, Hirudinea, Nematoda and Arachnida each had 1 species in the population. General diversity indices ranged from 2.02 to 2.78 with the least and highest recorded in Edion and Etuno Rivers, respectively. The fauna evenness index indicated that the water bodies had values less than 1.0. Meanwhile, Pollution tolerance index revealed spatial and seasonal variations in water quality conditions but only Edion River exhibited poor water quality in all the months of study.

Objective: Air pollution is one of the major global tribulations in many developing cities around the world. Addressing this sort of pollution is more intricate than other ecological challenges. As pollution is an upcoming issue, we aimed at assessing the air pollution tolerant plants from roadside exposed to vehicular air pollution from two different locations in Thane city.Methods: In the present study, commonly available ten roadside tree species selected from polluted and control area, and their air pollution tolerance index (APTI) determined in Thane city. The biochemical parameters viz. pH, ascorbic acid, total chlorophyll, relative water content (RWC) were considered to calculate APTI by using standard method.Results: The study shows that the control site has more APTI than the polluted site. The APTI observed minimum in Tectona grandis 5.2±0.3247 and maximum in Azadirachta indica 13.5±0.4404. Reduction in APTI at polluted site shows that Alstonia scholaris (6.6%), Tamarindus indica (8.8%) and Azadirachta indica (10.3%) were the most tolerant tree species, while Tectona grandis (47.5%), Acacia nilotica (27.4%) and Cassia fistula (20.7%) were more sensitive tree species. The results showed the order of tolerance (% difference in APTI) as Alstonia scholaris (6.6%)>Tamarindus indica (8.8%)>Azadirachta indica (10.3%)>Moringa pterygosperma (11.9%)>Mangifera indica (13.9%)>Bahunia variegate (14.3%)>Annona squamosa (18.7%)>Cassia fistula (20.7%)>Acacia nilotica (27.4%)>Tectona grandis (47.5%).Conclusion: Tolerant trees species can serve as a sink, and sensitive tree species can act as an indicator for air pollution mitigation. Thus, this study provides useful insights for selecting tolerant species for future planning and Greenbelt development in urban areas.

Air Pollution Tolerance Index

Industrialization is an important aspect of a growing economy. However, rapid industrialization has caused many serious impacts on the environment. One such impact is the deteriorating air quality, especially around industries. It is said that afforestation is the best and simplest way for improving the air quality. Also, trees and plants have been increasingly used as filters for dust particles around the home, traffic roads, etc. In scientific studies, it has also been found that trees and plant leaves can be used to assess the ambient air quality by an index called the Air pollution tolerance index. A literature search has been done on the scientific database like Sciencedirect and Researchgate to review the existing knowledge of Air pollution tolerance index and to find the tolerant and sensitive species based on it so that these species can be selectively planted to assess the ambient air quality and also to develop a better green belt around refineries and industries in Assam. The study has reviewed the linkage of the impact of air pollution on leaves of plants and trees through scientific evidence. Through such scientific reviews, the most tolerant species of trees and plants were chosen with the condition that it can grow under the climatic condition of Assam. The recommendation and suggestions of tolerant tree and plant species can be used for specific species plantations for developing green belts around refineries and industries in Assam. The recommendation of sensitive species can be used for monitoring ambient air quality with reference to other standard procedures.

Response of plants towards air pollution is assessed by air pollution tolerance index (APTI). Four species of Gymnosperms (Thuja orientiales, Cedrus deodara, Pinus roxburghii and Araucaria bidwillii) were evaluated for APTI. Leaves were collected during winter season from polluted sites (Airport, Dhumbarahi, Jawalakhel, Ratnapark, and Sankhapark) and less polluted site (Narayanthan) of Kathmandu valley. Of four gymnosperm species collected from road side, all species (Cedrus deodara, Araucaria bidwillii, Thuja orientiales and Pinus roxburghii) showed high value of APTI (i.e., more than 8), indicating their resistance to air pollution.ECOPRINT 24: 13-19, 2017

Air pollution due to huge number of vehicles emitting toxic gas poisons both living environment affecting fauna and flora. Road side plants are affected mostly by pollution as they are primary acceptors and gets reflected in terms of tolerance and sensitivity to pollution. Hence, the present work was designed to study the air pollution tolerance (APTI) using biochemical parameters and anticipated performance index (API) of the plants collected near seven different locations. Among the plants assessed, all plants selected does not show much difference in ascorbic acid, total chlorophyll, pH, relative water content, but that slight difference exhibited variations in air pollution tolerance index. Pongamia pinnata (33.16), Ficus religiosa (34.05) Near Asian rubber Industry, Kandampatty Byepass, Salem was found to be a tolerant species, Polyalthia longifolia (8.21) as very sensitive in plants studied Near KMB Granites Pvt. Ltd. Kottagoundampatty, Salem, and the rest was found to be moderately tolerent. Since, the studied plants show lesser surface area, the amount of dust collected was also less, which might be due to the climatic condition prevailed at that time of sample collection. Likewise, the API was found to be excellent in Yercaud lake view and very good in study area Duroflex company, Karimangalam, Dharmapuri, poor in study area Thanithotty Quarry, Salem as well as in KMB granites Pvt.Ltd. and good for the remaining three locations. So, the sensitive plants has to be protected that are located in these sites to reduce the pollution load.

Background: In the present study, the tolerance of plantain tree species (Platanus orientalis, Morus nigra and Ailanthus altissima) to air pollution was evaluated using Air Pollution Tolerance Index (ATPI) and Anticipated Performance Index (API) index in Isfahan city (Iran). Methods: For this purpose, three dominant trees growing at six stations in Isfahan was selected and then sampling of the tree leaves was performed, after being transferred to the laboratory, the ATPI and API index were calculated. Results: The results of calculating the ATPI in the leaves of M. nigra, P. orientalis and A. altissima species showed that the highest values of ATPI index was obtained in M. nigra at 20.77 and then detected in P. orientalis and A. altissima with the values 14.90 and 14.33 respectively. According to API values Morus nigra had the best performance (Score = 6 so it classified as the Excellent) while P. orientalis and A. altissima had very good and intermediate performance, respectively. Conclusion: According to ATPI and API index most tolerant tree species was Morus nigra, so it would be the most suitable species for plantation programme in urban and pollutant areas followed by Platanus orientalis and Ailanthus altissima. As well as our results suggest that Platanus orientalis and Ailanthus altissima can be used as bio-indicators of air pollution due to their low ATPI scores (lower than 16). The present study suggests that the combination of both the ATPI and API indices for identifying and selection of plant species is very useful for plantation in urban areas.
