Soil contamination occurs when contaminants are present in soil above safe levels, deteriorating soil functions. It occurs through point pollution from specific events or diffuse pollution of low contaminant levels spread widely. Human activities are the main source, such as industry, agriculture, and waste. Contamination decreases soil biodiversity, stability, and decomposition, increasing erosion risk. It harms biomass production, nutrient storage and filtering, and gene pool diversity. Soil pollution contains toxic chemicals that pose health or ecosystem risks, and is mainly caused by improper waste disposal and industrial/agricultural activities. Common pollutants include heavy metals, pesticides, and polyaromatic hydrocarbons.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. SOIL CONTAMINATION
Is the occurrence of
contaminants in soil above
a certain level causing
deterioration or loss of one
or more soil functions.
3. SOIL CONTAMINATION
OCCURS IN TWO(2) FORMS
Point pollution caused by a specific event or series
of events to a particular place, such as a former
factory sites. This is relatively well mapped and
understood.
Diffuse Pollution this involves low levels of
contaminants spread over very wide areas that
become lodged in the soil as it acts as a sink. This is
difficult to analyze and track. Examples of such
contaminants would be heavy metals or herbicides
or pesticides used in agriculture.
5. HUMAN ACTIVITIES
The most important
sources of contamination in
soils are those connected
with human activities.
6. How does it interact with other soil threats?
Soil contamination leads to decreased
activity of soil biodiversity and therefore to
a decline of aggregate stability and in
decomposition processes. Strong correlation
can also be seen between contamination and
erosion. A decline in aggregate stability and
organic matter caused by soil pollutants
increases the erodibility and therefore the
risk of wind and water erosion.
7. Landslides, flooding, wind
and water erosion may also
lead to pollutants being
transported off site as
solutes or particles and in
turn pollute the connected
aquatic environment or
soils downslope.
8. HOW DOES IT AFFECT SOIL
FUNCTIONS?
Biomass production – a contaminated soil
loses the productivity and the capacity to
support plants properly.
Storing, filtering and transforming – these
functions are all disrupted or prevented in
contaminated soil. In particular, organic
matter decomposition can be disrupted
affecting the cycling of nutrients.
9. Gene pool (biodiversity) –
plants, microorganisms and
enzyme activity in the soil is
disrupted and lessened in
contaminated soil, leading to a
decline in soil biodiversity.
10. SOIL POLLUTION
Is defined as the presence of toxic chemicals
(pollutants or contaminants) in soil, in high enough
concentration to pose a risk to human health
and/or the ecosystem.
In the case of contaminants which occur naturally
in soil, even when their levels are not high enough
to pose risk, soil pollution is still said to occur if the
levels of the contaminants in soil exceed the levels
that should naturally be present.
11. 2 MAIN CAUSES THROUGH
WHICH SOIL POLLUTION IS
GENERATED:
Natural causes
Anthropogenic (man-
made) causes
12. NATURAL POLLUTANTS
Natural processes can lead to an
accumulation of toxic chemicals in the soil
this type of contamination has only been
recorded in a few cases, such as the
accumulation of higher levels of perchlorate
in soil from Atacama Desert in Chile, a type of
accumulation which is purely due to natural
processes in arid environments.
13. MAN-MADE POLLUTANTS
Man-made contaminants are the main causes of
soil pollution and consist of a large variety of
contaminants or chemicals, both organic and
inorganic. They can pollute the soil either alone or
combined with several natural soil contaminants.
Man-made soil pollution is usually caused by the
improper disposal waste coming from industrial or
urban sources, industrial activities, and agricultural
pesticides.
14. TYPES OF SOIL POLLUTANTS
Biological agents – works inside the soil to
introduce manure and digested sludge
(coming from the human, bird and animal
excreta) into the soil
Agricultural practices – the soil of the crops is
polluted to a large extent with pesticides,
fertilizers, herbicides, slurry, debris, and
manure.
15. Radioactive pollutants – radioactive
substances such as Radium, Thorium,
Uranium, Nitrogen, etc. can infiltrate the soil
and create toxic effects.
Urban waste – consists of garbage and
rubbish materials, dried sludge and sewage
from domestic and commercial waste.
Industrial waste – steel, pesticides, textiles,
drugs, glass, cement, petroleum, etc. are
produced by paper mills, oil refineries, sugar
factories, petroleum industries and others.
