AIR POLLUTION

AIR POLLUTION

• Issues

• Solutions

• Barriers to Implementation

PARTICULATE AIR POLLUTION

SOLUTIONS

• Cost effective

• Be effective make a difference with measurable results

• Not take up valuable space

• Not be subject to Planning and Policy issues

Various studies have shown exposure to nature helps in:

Promoting Mental Health:

•Stress recovery

•Attention restoration

•Reduced prevalence of mental

disorder

•Trust, tolerance, participation,

feelings of safety

Green spaces and links also promote

direct physical activity

•Walking

•Cycling

•Running

•Green gyms

Health & Wellbeing

Gas and Aerosol Removal

•Absorbs pollutants:

cleaning the air

•Carbon capture –

takes up CO2

•Gives off oxygen

GI is Multifunctional !sustainable urban drainage

Moderates urban climate

Visual amenity

Shade for adjacent

properties and humans

Gives off O2

Takes-up CO2

Absorbs pollutants Removes dust and

particulates

Increases property

prices

Wildlife habitat

And that is just one tree

Particulate entrapment

Particulate entrapment – on ivy

Conclusions

Removes large quantities of Particulate Pollution

But

We don’t know how much relative to the whole

We don’t know where the particulates are going

Rainfall

Wind

WE SUSPECT

Rainfall has a marked effect

Southside work showed 14million particulates per square meter per day

were removed.

IF

We assume rain removal of particulates ( reproduced in the lab) then this

figure COULD rise to 3184 million particulates per square meter per day

• PM 0.1 to 10 Reduced by 96%

• PM 0.1 to 2.5 Reduced by 98%

SOME OF THE THINGS WE DON’T KNOW

• How long will it work without a significant reduction in efficiency

• How often will it need cleaning

• What rates of air flow produce the best results

• The configuration of the differing parts to achieve maximum success

VIDEO ANALYTICS

• Count vehicles into their various

classifications (Cars, HGV, Black Cabs,

Vans, Bikes)

• Highlight and manage illegal parking in

real time

VIDEO ANALYTICS

• Provide a full carpark management system which allocates spaces before a journey and starts and charges in real time for parking

• Provide a fully integrated traffic and travel management system

VIDEO ANALYTICS

• Ready to go

• Is not subject to false alarms due to camera jitter or changing light levels

• Can use all existing camera systems and infrastructure

VIDEO ANALYTICS

• Can be applied to security issues

• Can be applied to people

• Identifies and measures behaviour and highlights events in real time
