Influence of land use on total suspended solid and dissolved ion concentrations: Baton Rouge, Louisiana area

Abstract

Past studies in the Baton Rouge, Louisiana area considered streamwater quality during storm events but ignored water quality during low flow periods. This study includes determination of streamwater quality during low flow time periods for none watersheds in East Baton Rouge Parish, Louisiana. These samples were collected during dry-low flow periods as indicated by water levels at USGS stream gauging sites for each stream. Chemical analysis for ions was completed using colorimeters and gravimetric analysis for total dissolved solids (TDS) and total suspended solids (TSS). Land use appears to impact concentrations of ions, TDS and TSS in a variety of ways during periods of low flow. The two most rural watersheds, which are mainly underdeveloped, have higher concentrations of Fe and Mn. By contrast the three most urban watersheds, that are mainly commercial, industrial or residential, have higher concentrations of Si, SO4 and TDS.

Tingkat dan laju penurunan kualitas air di DAS Brantas Malang Raya

“…Total dissolved solid (TDS) merepresentasikan keseluruhan padatan terlarut berupa mineral yang ada di dalam air (Islam et al, 2016). Mineralmineral di dalam air sungai bisa disebabkan karena 2 faktor, yaitu input mineral dari luar (Anhwange et al, 2012;Carlson, 2014) dan produk dari dokomposisi bahan organik yang ada pada air sungai tersebut (Wu dan Maskaly, 2018). Titik A, B, C, dan D (Kota Batu dan Malang bagian barat) masih menunjukkan tingkat dekomposisi seimbang, tetapi pola yang sama tidak terlihat pada titik E, F, G, dan H (Kota Malang).…”

Assessing the Impact of Land Use and Land Cover Change on Air Quality in East Baton Rouge—Louisiana Using Earth Observation Techniques

“…Also, various forms of Land Use Land Cover (LULC) activities prevalent in the major urban centers can affect the quantity of PM [4]. Consumption of energy, emissions from industries, and automobile traffic all rise when cities expand in size and population, both of which can negatively impact the quality of air [5]. PM is also caused by the generation of particles from released gases, including Nitroxide (NO 2 ), Volatile Organic Compound (VOC), and ammonia [5].…”

“…PM2.5 refers to particles with a smooth diameter of not more than 2.5 m, which are tiny enough to be breathed. Numerous studies have linked extreme pollution episodes to a higher incidence of disease and fatalities over the last century [5]. In the past few decades, attention has switched to the effect of the extended contact with PM in the medium levels, as observed in populated areas.…”

“…There have always been several primary causes of air pollution, but there are also secondary causes of pollution by particles that occur from chemical interactions in the lower stratosphere. PM is also caused by the generation of particles from released gases, including NO 2 and VOC, and ammonia [5]. Furthermore, air pollution can be carried from one place to another, making the matter much more complicated.…”

Analisa Dan Pemetaan Total Padatan Terlarut Di Pesisir Pantai Pasuruan Dengan Citra Satelit Terra Modis

“…Total Dissolved Solid (TDS) mengandung berbagai zat terlarut (baik itu zat organik, anorganik, atau material lainnya) dengan diameter < 10,3 µm yang terdapat pada sebuah larutan yang terlarut dalam air (Brando et al, 2006;Carlson, 2014;Ratnaningsih et al, n.d.). Padatan terlarut termasuk salah satu faktor penyebab kekeruhan di air (Wibisana et al, 2019;Wibisana & Zainab, 2017).…”
