“…The lower amount of chlorophyll a, chlorophyll b, total chlorophyll and carotenoids under polluted environment were also noted in several other studies (Singh et al 1985;Singh et al 1990;Malabari et al 1991;Dhir et al 1999;Nighat et al 1999Nighat et al , 2000Saquib, 2008;Iqbal et al 2010;Chauhan and Joshi, 2010). Several researchers have reported reduced carotenoid content under air pollution (Joshi et al, 2009;Tiwari et al, 2006…”

The effect of industrial emissions on the levels of certain biochemical measurements in leaves of Camphor (Cinnamomum camphora), Henna (Lawsonia inermis), and Bougainvillea (Bougainvillea spectabilis) trees growing in the industrial zone in Jeddah -Saudi Arabia and Hada Al-Shame area (control) was done. Overall results showed that the content of chlorophyll a and b, total chlorophyll, carotenoids and protein in the plant leaf of the trees growing in the industrial zone were less comparing with the leaves of the trees growing in the control area.

“…Consistent with such findings, both high CO 2 (Reid et al 1998;Schwanz and Polle 2001;Lin and Wang 2002) and high SO 2 (Singh et al 1985;Kong et al 1999;Hongfa et al 2000) may cause increases in carotenoid concentrations. The lowest carotenoid concentrations were observed in P. nigra.…”

“…The chl contents of many plants decrease when treated with SO 2 (Singh et al 1985;Kong et al 1999), with the reduction being greater for chlb than for chla (Singh et al 1985). In addition, elevated CO 2 can reduce chl contents (Gielen et al 2000).…”

In order to assess the impact of SO 2 , CO 2 , NO x , and CO on non-enzymatic foliar defense mechanism around oil refineries, the present study was undertaken in Batman, Turkey during the periods February-April-June 2002. For this purpose, the four common evergreen plants at all sites, Pinus nigra Arn. subsp. pallasiana (Lamb.) Halmboe, Ligustrum vulgare L., Thuja orientalis L., and Nerium oleander L. were selected as test plants. Four study sites were selected at the Batman Refinery area (AR). Four control sites were also selected at a distance of about 5 km from the refinery (OR). Responses to oil refinery pollution of plants, heavy metals, chlorophyll (chl), proline, carotenoids, lipid peroxidation, SH-compounds, and ascorbic acid were measured. In addition, ambient pollutant gas concentrations were measured. The pollutant gas concentrations were high in the immediate vicinity of oil refinery. The levels of total chl, SH-compounds, ascorbic acid, and chla/chlb ratio were found to decrease, and the amount of proline, carotenoids, lipid peroxidation, and reduced ascorbate/oxidized ascorbate ratio were found to increase in comparison to plants growing at the control sites. A comparison of four evergreen plant species indicated that L. vulgare was the most resistance to refinery induced air pollution and the magnitude of foliar injury symptoms was greatest in P. nigra and T. orientalis.

“…Earlier workers have suggested that chlorophyll a is more sensitive than chlorophyll b in a polluted atmosphere (Singh et al 1985, Singh and Rao 1986, Wali et al 2004. But present data revealed that percent reduction in chlorophyll a and b is almost equivalent.…”

The effect of coal smoke pollution on the biomass and chlorophyll pigments of Brassica juncea were studied at 0.5, 2, 4, 6 and 20 km distance leeward from a thermal power plant complex. The root, shoot and total biomass and chlorophyll a, chlorophyll b and total chlorophyll were significantly reduced up to a distance of 4 km from the source of pollution. The data indicates that the degree of response increased with decreasing distance from the source of pollution in comparison to the reference site ‘c' situated at 20 km. Biomass and chlorophyll pigments showed a significant and positive relationship with the distance from the source. Key words: Air pollution, Brassica juncea, biomass, chlorophyll. doi: 10.3126/eco.v15i0.1935 ECOPRINT 15: 1-6, 2008
