“…In some of the studies carried out on this subject, the usability of oyster shell [76], olive wastes [77], forest wastes [78], fig wastes [79], rise husk ash [80,81] and some of the other materials [82,83] as concrete additive was examined. Environmental pollution has increased dramatically, especially in the last 30 years [84][85][86] and because of the rapid development of global economy, the type and level of chemical pollution have constantly increased, and this increase has reached a terrifying level for the ecosystems [87,88]. In order to effectively control the pollution, using waste materials as concrete additive will help protect the environment and conserve natural resources.…”

Palm leaves are vegetal waste that are not widely used by the society, only piled up and causing odors that mix with the environment. Channeling this waste material into the construction industry helps to overcome waste disposal problems as well as promote sustainability. The most important features expected from the buildings are the creation of the most suitable environmental conditions for the products to be stored or the creatures that will live in them, and they can be used safely for a long time. In the construction of the buildings, materials that are the cheapest possible, safe and capable of creating the optimum environmental conditions should be used. The materials to be selected should have sufficient strength and durability, high heat and sound insulation and lightness. Since single-storey buildings are not subject to excessive load, it is important that the thermal insulation is high and light in material selection. Since the widespread use of concrete as a building material in the world, efforts to make concrete light, cheaper and better insulating have gained importance. Lightweight concrete, which is easy to apply, has been an important building material in recent years. With the use of lightweight concrete as a building material, benefits such as economy in terms of material, earthquake resistance, and the elimination of a second insulation material for heat and sound insulation can be achieved. In this study; Experimental study using Portland cement (CEM I), Palm Leaf, CEN standard sand and water mortar production; sample production, curing, some physical and mechanical experiments were carried out in four stages. The usability of palm leaf, which is a vegetable waste, as aggregate in concrete production by replacing it with CEN standard sand at 0, 5, 10, 20, 30 and 40% as well as 10% with cement has been investigated. The study results show that the addition of both ground palm leaf and palm leaf aggregate significantly altered almost all properties of concrete. These changes are at different levels in terms of physical properties. As a result of the study, it was determined that as the amount of foam increased, the spreading diameter increased, whereas palm leaf addition decreased the spreading diameter. It has been determined that the addition of palm leaf decreases the depth of water treatment depending on time, the porosity of the samples with high level of palm leaf addition increases and the compression and bending strength decreases.

“…This is because these elements cause stress in plants. As well as many factors including temperature, water deficiency, UV-B, diseases, pests, air pollution, etc., heavy metals can also decelerate plant growth and even cause death by creating stress in plants [43][44][45][46][47][48][49][50].…”

The advancements worldwide in the last century made air pollution one of the most important problems threatening human health on a global scale. One of the most harmful components of air pollution is heavy metals. For this reason, monitoring and reducing heavy metal pollution has been one of the main research subjects in recent years. In the present study, the accumulation of Mn, Zn, Ba, and Sr, which were included in the preliminary pollutant list by ATSDR (Agency for Toxic Substances and Disease Registry) since they pose a significant threat to human health, by plant species and organ was investigated. As a result of the present study, the highest concentrations were found in the leaves. The most useful species to be utilized in monitoring the change of the concentrations of heavy metals examined here in the air and to reduce the level of pollution were found to be Cotoneaster franchetii and Platycladus orientalis.

“…Moreover, previous studies showed that even the heavy metals that are necessary as nutrient element for organic development might be harmful to health when at high concentrations [35][36][37][38]. For this reason, many studies have examined the concentrations of heavy metals in soil [39,40], water [41][42][43], and air [44][45][46][47][48][49]. In recent years, the studies carried out on heavy metals were diversified more and many studies were carried out on heavy metal pollution caused by heavy metal sources such as traffic [50][51][52][53], industry [54], urban areas [55], and mining fields [56].…”

Concrete additives started to be used commonly in order to reduce the cost of concrete, which is widely used in construction industry, and to recycle some wastes that are harmful to the environment. However, these additives might include heavy metals that are very harmful to human and environmental health and the number of studies on this subject is very limited. Besides the health of individuals working in this industry, it also creates a lack of knowledge about the environmental effects of construction activities. In the present study, among the heavy metals that can be very harmful to human and environmental health, Co, Bi, and Mg concentrations in some concrete additives were examined. The results showed that heavy metal concentrations in various concrete additives including copper slag, vermiculite, brick dust, Cem III cement, and blast furnace slag were very high. It might pose a risk to the health of individuals working in this industry, as well as the environmental health.
