The present work may indicate that cement dust greatly affected the salt marsh adapted species, A. glaucum, H. strobilaceum and S. fruticosa, by destroying the photosynthetic processes, disturbing the pH of the cell sap, decreased total nitrogen and interrupted the metabolism of soluble amino acids and soluble sugars into insoluble reserve substances.
Leaf structural traits of tropical woody species resistant
Cement industries located nearby limestone outcrops in Brazil have contributed to the coating of cement dust over native plant species. However, little is known about the extent of the response of tropical woody plants to such environmental pollutant particularly during the first stages of plant development and establishment. This work focused on the investigation of possible alterations in
Cement Dust an overview | ScienceDirect Topics
Emissions of cement dust are strictly controlled by the use of dust-extraction systems in loading areas, cement silo filter systems, restrictions on powder-blowing pressures and the provision of high-level silo alarm systems. Many plants now have water-recycling systems which minimize the amount of water being discharged from the site. All wash-out and surface water is stored, any excess

Germination of Medicago sativa is inhibited by soluble
Deposition of cement dust on soils and plant surfaces is known to affect plant growth and the species composition of plant communities, but little is known about its effects (and those of its pH and constituents) on germination. Therefore, the aim of this study was to assess the toxicity of an aqueous cement extract, constituents of the extract and pH on the germination of seeds of a selected
Chlorophyll content of six tree species under influence
The present study aimed to analyse the effect of a cement plant emissions of dust on chlorophyll content of six tree species. Chlorophyll content was evaluated monthly during a year on trees growing at two different places: one under the influence of cement dust and the other 50 km far from this type of emission. Pigments were extracted with dimethylsulphoxide and its concentration measured by...

cement dust on pigmentation was studied in Azadirachta indica, Pongamia pinnata, Delonix regia, Polyalthia longifolia and Ficus religiosa. Sampling was Sampling was done about 500 meter distance difference from the cement industry and measurements were taken for all the plant species spectrophotometrically.
Effects of Cement Dust on the Physiological Activities of
Air pollution exerts detrimental effects on plant ecosystems and restricts agricultural productivity. Cement dust is considered to be one of the most harmful air pollutants of industrial origin and is a limiting factor for plant growth and productivity. This study aims to uncover the impacts of cement dust on photosynthetic pigments, protein content, hydrogen peroxide (H2O2) accumulation

Vegetation responses to long-term alkaline cement dust
Questions How resilient is boreal forest vegetation growing on acidic podzols to the environmental change caused by alkaline kiln dust pollution? How adaptive is the vegetation, when species pool and time for dispersal do not limit? How constant is the species niche breadth along the soil pH gradient?

FOREST SPECIES SHOW A DELAYED RESPONSE TO CEMENT
DELAYED RESPONSE TO CEMENT DUST IN THE SOIL by Ann F. Rhoads1 ABSTRACT Severe foliar chlorosis, leaf scorch and accompanying branch dieback, and mortality of native oak species presently occurring on a 300-acre site in northwestern New Jersey have been associated with deposition of cement dust which occurred from 1903 to 1940. Because soil pH values in the affected area are
Study of cement dust retentivity of various plant
Abstract: Cement dust retention capacity of leaves of different trees and plants has been investigated. The results indicate that Neem leaves have the highest capacity. The dust retention capacity of each type of leaf was calculated as- Dust retention capacity = W x 10 3 / A, where A is area of leaf in cm 2 and W is weight of dust retained in gm. For several decades, air pollution from cement
