TL;DR: Awal et al. as discussed by the authors explored some of the possible factors involved, focussing particularly on the relationship among the amount of top-dying in different places and the human destruction of Sundarbans ecosystem as well as abnormal concentrations of a number of chemical elements present in the soil, in order to test the hypothesis that ecological pollution, along with chemical pollution might be responsible.
Abstract: Coastal belts render energy & operative support to people and natural resources (Awal, M.A.2007). But the Sundarbans is being contaminated by various environmental factors such as heavy metal contaminations in soil and water as well as people health (Awal, M.A. 2014). So, a questionnaire survey was conducted among different groups of people inside and outside of Sundarbans to explore local perceptions as to the possible causes of disease of plants in Sundarbans (Awal, M.A.2009). This confirmed the increase in top-dying prevalence. Despite various hypotheses as to the causes of this top-dying, the underlying causes are still not well understood. The present work has explored some of the possible factors involved, focussing particularly on the relationship among the amount of top-dying in different places and the human destruction of Sundarbans ecosystem as well as abnormal concentrations of a number of chemical elements present in the soil, in order to test the hypothesis that ecological pollution, along with chemical pollution might be responsible. Of the hypotheses previously put forward to explain top-dying, the present results do not support enhanced salinity as the cause. It is likely that several of the above-mentioned environmental factors interact with each other to induce top dying in Sundri (Awal, M.A. 2004). However, the present results have showed that Sn, Exchangeable K, soil pH, Pb, Zn and Ni could be directly linked with top-dying disease of Heritiera fomes (Sundri) in Sundarbans, probably particularly by weakening the vigour of the trees and people and allowing other factors such as pathological agents to attack the plants and surrounding people in Sundarbans, Bangladesh (Awal, 2014).

TL;DR: In this article, the authors explored some of the possible parameters involved, focussing particularly on the relationship between the amount of top-dying in different places and the concentrations of a number of chemical parameters present in the soil, in order to test the hypothesis that chemical pollution might be responsible.
Abstract: A Sundarbans mangrove in Bangladesh is facing tremendous problems of heavy metal contaminations in soil (Awal, 20014). The present work has explored some of the possible parameters involved, focussing particularly on the relationship between the amount of top-dying in different places and the concentrations of a number of chemical parameters present in the soil, in order to test the hypothesis that chemical pollution might be responsible (Awal, 2014). Other factors such as the pH, salinity and nutrient status were also assessed (Awal 2014). Nine plots were selected for sampling of soil in order to categorise different areas in terms of their intensity of top-dying (Awal 2007). 63 soil samples were tested, mainly by ICPMS, to investigate certain parameters of the soil such as Sn, Exchangeable K, Soil pH, Pb, Zn, Ni, EC, soil nutrients, soil moisture content, and elemental concentrations of 32 other elements (Awal 2009). The vegetation structure was assessed in terms of tree height, bole diameter, species present, and regeneration status; and the intensity of top-dying within the plots was recorded on a rank scale. Most of the elements studied had no significant correlation with the top dying of Heritiera fomes. However, Sn, Exchangeable K, and soil pH were significantly related, and three elements, namely Pb, Zn, Ni, were also close to significance (Awal, 2007). Sn concentration is negatively associated with top dying. Soil pH varied significantly in the different plots (Awal 2007). Exchangeable K was positively associated with the tree diameter whether the top dying was severe or mild (Awal 2007). However, the present results have showed that Sn, Exchangeable K, soil pH, Pb , Zn and Ni could be directly linked with top-dying of Heritiera fomes (Sundri) in Sundarbans, probably particularly by weakening the vigour of the trees and allowing other parameters such as pathological agents to attack the plants (Awal, 2007).

Abstract: For centuries the area which is now Bangladesh was known throughout the civilized world for its fabled wealth, of which the exquisite muslin, Sundarbans, Cox’s Bazar un-broken sea beaches were the apt symbol. Aryans, Turks, Mughals, Afghans, Arabs, Dutch, Portuguese, French and British were attracted by the opulence of Bengal. They came as invaders, traders, settlers, missionaries and in their different ways, contributed towards making this country a distinctive entity among the world’s nations, boasting numerous historical and natural assets. However, this is kaleidoscopic presentation of our land called coastal belt in Bangladesh, its valiant people imbued with a sense of history, its rich and flora and fauna, its verdant landscape with lush green fields, enchanting hills and hillocks and the meandering rivers falling into the vast blue expanse of the Bay of Bengal. It is a land of enormous economic potentials, inhabited by diligent and hard-working people who have a love for heritage. It is a land of ancient and variegated religious and cultural traditions. All of these together make Sundarbans a colorful mosaic of nature’s splendor and bounty (Awal, 2014). Despite various hypotheses as to the causes of this natural degradation, the underlying causes are still not well understood. The present work has explored some of the possible factors involved, focusing particularly on the relationship among the environmental factors and the human destruction of Sundarbans ecosystem as well as abnormal concentrations of a number of chemical elements present in the soil, in order to test the hypothesis that ecological pollution, along with chemical pollution might be responsible. However, the present results have showed that Sn, Exchangeable K, soil pH, Pb , Zn and Ni could be directly linked with top-dying disease of Heritiera fomes (Sundri) in Sundarbans, probably particularly by weakening the vigor of the trees and people and allowing other factors such as pathological agents to attack the plants and surrounding people in Sundarbans, Bangladesh (Awal, 2014). In fact, from since then and still now, the natural resource of Bangladesh like Sundarbans is being disturbed ecologically by human destruction.
