Objective: The present work investigates the metal uptake of the plant Ficus religiosa leaves collected from nine experimental sites in Gorakhpur, Uttar Pradesh. Materials and Methods: The concentration of lead in leaves was determined with help of atomic absorption spectrophotometer. Results: The level of the lead in leaves of Ficus religiosa was much higher than the limits recommended by World Health Organization (WHO). The bioaccumulation of lead was highest in site 2 (Gayatri nagar) i.e. 14.1 mg kg-1 dry weight of F. religiosa. To determine the relationship between the lead concentration in leaves and traffic density the Pearson\’s correlation analysis has been performed. Conclusion: The value of Pearson\’s correlation coefficient was positive indicating that the traffic density plays an important role in the lead pollution in plants.

Objective: The effect of chlorophyllin (CHL), CHL + freeze dried cow urine (FCU) and FCU on acetylcholinesterase (AChE) and cytochrome oxidase activity in the nervous tissue of the host snail Lymnaea acuminata, and parasitic cercaria larvae of Fasciola gigantica were studied. Methods: Whole cercaria larvae and snail nervous tissue was homogenized and supernatant was used as an enzyme source. Enzyme activity was measured in 10-mm path length cuvette using incubation mixtures and change in optical density was recorded. Results: Sublethal 4 h LC50 40\% and 80\% of these formulations in sunlight and laboratory conditions caused no significant change in AChE activity in the nervous tissue of host snail. It was noted that sublethal in vivo 8 h exposure to 40\% and 80\% of 4 h LC50 of single and binary combination of CHL+FCU, CHL and FCU significantly altered the AChE and cytochrome oxidase activity in the cercaria larvae. Binary combinations of CHL+FCU in sunlight were more effective in inhibiting both the enzymes. Conclusion: The present study reported that enzymes AChE and cytochrome oxidase were inhibited by chlorophyllin formulations and thus causing the larval death inside the snail body without affecting the snail itself which is an important bioindicator of aquatic ecosytem.

Introduction: Paper demonstrates effect of the active molluscicidal components arjunolic acid (Terminalia arjuna bark) and procynadine (Tamarindus indica seed) on the activity of acetylcholinesterase (AChE) and phosphatases (ACP/ALP) in the cerebral ganglion of snail Lymnaea acuminata. Materials and Methods: Kinetics of AChE/ACP/ ALP inhibition in the cerebral ganglion of snail Lymnaea acuminata was studied via in vivo (40\% and 80\% of 96 h LC50) and in vitro treatments (0.3 g to 7.0 g) of the column purified fractions, arjunolic acid and procynadine. Results: In vivo exposure of procynadine and arjunolic acid significantly inhibit acetylcholinesterase (AChE), acid phosphatase (ACP) and alkaline phosphatase (ALP) activities in the cerebral ganglion of L. acuminata exposed to 80\% of 96h LC50. In in vitro treatment maximum inhibition in AChE/ACP/ALP activities in the cerebral ganglion of snail were noted when exposed to 7.0 g of arjunolic acid and 0.9 g of procynadine. Column purified fraction of T. arjuna bark and T. indica seed caused non-competitive and uncompetitive inhibition of AChE activity, respectively. Column purified fraction and arjunolic acid of T. arjuna bark caused uncompetitive inhibition of ACP while column purified fraction and procynadine of T. indica seed caused competitive inhibition. Competitivenon- competitive inhibition of ALP activity in the cerebral ganglion of L. acuminata was observed after treatment of column purified active components of both plants. Conclusions: The molluscicidal activity of T. arjuna bark (arjunolic acid) and T. indica seed (procynadine) against snail L. acuminata is due to the inhibition of AChE/ACP/ ALP. Their inhibition kinetics against AChE/ACP/ALP, were different in cerebral ganglion of snail.

Background: Fasciolosis is one of the most debilitating diseases caused by liver flukes Fasciola hepatica and F. gigantica. Snail Lymnaeidae and Planorbidae is the intermediate host of these flukes. Snail population management is a good tool to control fasciolosis because gastropods represent the weakest link in the life-cycle of trematode. Aim of the present study is to explore the molluscicidal activity of chlorophyllin in visible spectral band against Fasciola gigantica carrier snail Indoplanorbis exustus. Methods: Chlorophyll was transformed into water-soluble chlorophyllin in 100\% ethanol by using different types of chemicals. Ten snails Indoplanorbis exustus were placed in a glass aquarium containing 3 L of dechlorinated tap water. These snails were treated with different concentrations of chlorophyllin in sunlight as well as exposed to different visible spectral band of light. Results: Pure chlorophyllin (96 h LC50 6.54 mg/l) in sunlight was more toxic than extracted chlorophyllin (96 h LC50 939.65 mg/l). There was a significant variation in the toxicity of chlorophyllin with snails, exposed to visible spectral band of light. The highest and lowest toxicity of chlorophyllin against I. exustus was noted in yellow light (96 h LC50 2016.79 mg/l) and green light (96 h LC50 2433.16 mg/l). High performance liquid chromatography (HPLC) study reveals that the active molluscicidal component extracted in spinach leaves is chlorophyllin. Conclusion: Due to the photodynamic nature of chlorophyllin, it has the potential to control the population of vector snails and ultimately fasciolosis in developing countries.
